SPECIFICATION forming part of Letters Patent No. 667,177, dated February5, 1901.

Application filed May 31, 1900.

1'0 ctt!l whom, it 'may concern:

Be it known that I, SAMUEL E. BALL, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Machines for Cooling andMixing Fondants; and I do declare the following to be a full, clear, andeXact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters of refencemarked thereon, which form a part of this specification.

This invention relates to improvements in machines for mixing andcooling candy-cream for chocolate-creams, bonbons, &c. In thepreparation of the candy cream or stock for this class of confectioneryit is desirable in order to obtain the cream or fondant in a fine,smooth, and velvety condition that it be cooled rapidly and at the sametime agitated or mixed thoroughly. The sugar is boiled to a certainconsistency and is then placed in the vessel and is rapidly reduced to acold state before itis agitated. Unless the material is cooled rapidlyit goes through a process of crystallization and is rendered unsuitablefor the production of this class of confectionery, and the longer thematerial is permitted to hold the heat the more rapid is the formationof crystals. To obtain the desired results, I use a circular shallowreceptacle, the bottom of which is surrounded by a Water-jacket, andowing to the shallowness of said receptacle the top of the material orstock contained therein is enabled to come in contact with the air,which will have the effect of cooling the upper portion of the materialas it is being agitated. The agitatingblades are so constructed andarranged that the entire body of the stock is constantly moved in andout from the center of the receptacle in such a manner that thenecessary agitation is given said stock, as will be hereinafter morefully described in the specification and pointed out in the claims.

Referring to the accompanying drawings, Figure l is a top plan view ofmy invention. Fig. 2 is a vertical sectional view. Fig. 3 is anelevation of one of the blades. Fig. 4 is a perspective View of themachine complete.

Serial No. 18.500. (No model.)

Fig. 5 is an enlarged vertical sectional view of the bearings for theshafts.

The letter A represents a round shallow vessel in which the boiledmaterial or stock for the formation of the fondant is placed. Thisvessel is su rronnded throughout its sides and bottom with awater-jacket B, into and out of which cool water is made to constantlycirculate. The shallowness of this receptacle is an essential feature ofits construction, as it is important that the stock be submitted to thecooling effect of not only the waterjacket, but also the atmosphere.This receptacle is suitably mounted on legs O O and has a centralupright shaft D, which is driven through gearing from any source ofpower. The shaft D passes through asleeveD, which is stationary, havinga water-tight connection with the bottom of the receptacle. Dl is a plugupon the upper end of said sleeve. The shaft D passes through saidsleeve and plug and into the head D"', to which it is secured, so thatthe head D will turn with the shaft D. Secured to the head D" is ahorizontal shaft E. One end of said shaft E occupies a position adjacentto the rim of the receptacle, while the other end of said shaft isnearer the central shaft or the axis of the receptacle. There are placedon the ends of this horizontal shaft two stirrers or agitating-blades Fand F', which project a considerable distance from the ends of thehorizontal shaft and partake of the angles or curvatures substantiallyas shown in Fig. l. It will be noted from the length of these bladesthat a substantial body of the stock is carried around thereby and isreleased gradually at the end. The outermost one of said blades sweepsthe stock inwardly from the inner periphery of the vessel, while theinnermost one of said blades takes the stock on a line with the rear endof the outermost blade, as is shown in dotted lines, Fig. 2.

G designates an inner blade which is attached directly to the centralshaft. This blade in its rotation with the shaft and the other bladesthrows the stock out to a position to meet the outermost blade F in therotation of said blade. Owing to the arrangement and construction ofthese several blades IOO the stock is thoroughly agitated in acomparatively few rotations of the blades. As

shown in Fig. 3, these blades .havefa depth which is substantially equalto the depth of the vessel, so that in the rotation of said blades theentire body of the stock is carried around and a new surface in eachrotation is made to presentitself both to the water-jacket portion ofthe vessel and to the atmosphere. This is an important feature in theconstruction of the machine, as it is necessary that the stock be cooled'rapidly while it is being agitated, as hereinbefore specified.

H designates an inlet-pipe projecting into the bottom of the receptacleand through which water is introduced to the water-jacket, and H is asimilar pipe communicating with the upper portion of said receptacle andthrough which an outlet for the wat-er is provided.

Having described my invention, l desire to secure by Letters Patentl.The herein-described machine for cooling and stirring candy'stock, thecombination with a shallow vessel, having a waterjacket surrounding itsbottom and sides, an upright shaft projecting through the center of saidvessel, a horizontal shaft mounted above the Vessel, the point ofattachment of said horizontal shaft with the upright shaft being nearerone end of said horizontal shaft,

mixing-blades mounted on the ends of saidn horizontal shaft, the outerone of said mixing-blades being adapted to sweep the stock from theinner periphery of the vessel, and the innermost one of said bladesbeing adapted to sweep the stock which is left by the outer blade, aninner blade attached to said eer/317% upright shaft and being adapted tosweep the stock from the center of the vessel outward to the path of thetwo outer blades, substantially as shown and for the purposes specified.

2. In a machine for cooling and mixing fondante, the combination with ashallow vessel, the bottom and sides of which are surrounded by awater-jacket, an upright driving-shaft passing through the center ofsaid vessel, a horizontal shaft carried on the upper end of said shaft,the point of attachment of said horizontal shaft with the upright shaftbeing adjacent to one end of said horizontal shaft, elongatedmixing-blades mounted on the ends ofsaid' horizontal shaft, one of saidblades being adapted to scrape the inner periphery of the vessel, andthe other one of said blades being adapted to describe a circle whichcoincides with the circle described by the inner end of the outer one ofsaid blades whereby the stock is agitated by said blades from the innerperiphery of the Vessel, to a point adjacent to the axis of the vessel,and an inner blade attached to the upright shaft, the curvature of whichis concentric to said upright shaft, the inner blade being adapted tosweep the stock from the axis of the vessel outwardly iu the path of thetwo outer blades, substantially as shown and for the purposes specilied.

In testimony whereof I affix my signature in presence of two witnesses.

SAMUEL E. BALL.
